Abstract For the first time, Li2MoO4crystals depleted in molybdenum-100 (100Mo) isotope were grown by Czochralski technique under low thermal gradient conditions (LTG Cz) that made it possible to obtain large crystals of given geometry and required quality. Depleted lithium molybdate crystals Li2deplMoO4 are excellent candidates for creating cryogenic scintillating bolometers with weight of up to 0.3 kg. Such bolometers can be used to reduce the internal radiation background of detectors and to increase sensitivity in physics and astrophysics experiments for rare events search. The grown Li2100deplMoO4 crystal was compared with the crystal samples of natural and enriched in 100Mo isotope in regard of their response to pulsed X-ray irradiation and Raman spectra.

通过低热梯度直拉技术生长的 Li2100deplMoO4 晶体

摘要 首次在低热梯度条件 (LTG Cz) 下通过直拉技术生长了贫钼 100 (100Mo) 同位素的 Li2MoO4 晶体，这使得获得给定几何形状和所需质量的大晶体成为可能。贫化钼酸锂晶体 Li2deplMoO4 是制造重达 0.3 kg 的低温闪烁辐射热计的绝佳候选者。这种辐射热计可用于减少探测器的内部辐射背景，并提高物理和天体物理实验中罕见事件搜索的灵敏度。将生长的 Li2100deplMoO4 晶体与天然晶体样品和富含 100Mo 同位素的晶体样品比较它们对脉冲 X 射线辐射和拉曼光谱的响应。
